A delivery device includes a base body having an outlet opening and a chamber for receiving a flowable substance to be administered. The base body, having first and second film portions attached to each other by a connection with a plurality of regions, being configured to discharge the substance through the outlet opening by compressing the chamber. The delivery device further includes a pouring adapter tightly connected to the outlet opening. The plurality of regions of the connection include a more resilient region and a less resilient region that are arranged between the chamber and the outlet opening. When the chamber is compressed to discharge the substance through the outlet opening, the less resilient region is configured to come undone and the more resilient region is configured to remain connected so that the substance can be discharged solely through the outlet opening and the pouring adapter by compressing the chamber.

A respiratory interface assembly includes a patient interface, such as a nasal mask, and a headgear arrangement. The headgear arrangement can have one or more semi-rigid straps, which can be a composite construction of an outer fabric and a plastic core. The outer fabric can be knitted. The headgear arrangement can include a composite rear portion having an upper strap and lower strap, which are configured to be adjustable relative to one another.

A cannula includes a tubular body having an axial dimension through which a flow channel extends. The tubular body has a first end for insertion into a subject, and a second end configured to be held within a base of a medical device. The tubular body has a first length portion extending along the axial dimension from the first end toward the second end. A second length portion extends along the axial dimension from the first length portion toward the second end, and has an outer dimension that flares outward to be larger than the outer dimension of the first length portion. The second length portion also has a tubing wall thickness that is greater than the tubing wall thickness of the first length portion.

In some examples, a catheter assembly includes a catheter including an elongated catheter body defining a lumen, a first cuff and a second cuff. The first cuff includes a first cuff body comprising a material configured to promote epidermal tissue growth around or within the first cuff and an adhesive configured to adhere the first cuff body to an outer surface of the elongated catheter body at a first cuff position selectable by a user. The second cuff includes a second cuff body comprising the material configured to promote epidermal tissue growth around or within the second cuff body and an adhesive configured to adhere the second cuff body to the outer surface of the elongated catheter body at a second cuff position selectable by the user. A distance between the first and second cuff positions is customizable by the user based on a patient.

A pressure measurement pod for use in blood circuits includes a pressure sensing pod defining a chamber and having a rigid wall portion and an integral flexible wall portion forming a flexible, moveable, fluid-impermeable diaphragm with a first major side thereof facing an interior of the chamber and a second major side opposite the first major side. The second major side faces outwardly away from the chamber, and the pod has ports on sides of the chamber. The internal surfaces of the chamber and ports are shaped such that any contour following the internal surfaces to the outside of one of the ports traces only surfaces characterized by positive or neutral draft angles such that invasive mold portions may be withdrawn through the ports thereby permitting the pressure measurement pod to be molded in a single shot molding process.

A dry powder inhaler is disclosed. The dry powder inhaler includes a first housing member and a second housing member being rotatable in relation to one another to prepare administering a medicament dose from at least one medicament reservoir. An air inlet, a first air outlet, and a second air outlet are provided. The air inlet and the first air outlet are connected by a first air channel via a dosage mechanism configured to arrange a dose from the reservoir into the first air channel. The air inlet and the second air outlet are connected by a second air channel. An inhalation chimney is provided internally forming the proximal portion of the first air channel and comprising the first air outlet at a first end thereof.

A patient interface including a seal-forming structure with a textile membrane that has at least one hole such that the flow of air at a therapeutic pressure is delivered to at least an entrance to the patients nares and/or an entrance to the patients mouth. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout the patients respiratory cycle, in use. The textile membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The taut state of the second portion is configured to allow the seal-forming structure to include a three-dimensional shape that has multiple curvatures.

A one-piece medical connector has a unitary body. The unitary body includes a rigid portion that forms a housing. The unitary body also includes a resilient portion located at least partially within the housing. At least a movable portion of the resilient portion is configured to move relative to the rigid portion. Movement of the resilient portion selectively permits fluid flow through the connector. The rigid portion and the resilient portion form a one-piece unitary connector.

A method includes inserting into a patient body a medical suction tool, which includes a hollow first tube for removing material away from a Eustachian tube of a patient, and a hollow second tube disposed around the first tube. The medical suction tool is navigated to the Eustachian tube. The Eustachian tube is sealed by coupling an outer surface of the second tube to an inner surface of the Eustachian tube. While the Eustachian tube is sealed by the second tube, the material is removed away from the Eustachian tube via the first tube.

An apparatus having an adjustable ambient air-oxygen blender that adjustably mixes ambient air with an oxygen supply, especially where a size, diameter or flow rate of an orifice is mechanically adjustable so as to control a quantitative mixing function of the blender.
